Specification of Letters Patent.

Application filed March 1916.- Serial No. 87,781.

Ta all whom it may concern r Be it known that 1, JOHN J. TOKHEIM, a

citizen of the United States, residing at impurities which are removed from the gasolene.

Another object of the invention is to provide novel means for supplying gasolene to the apparatus, and to provide novel means.

for caring for the water of condensation pro- 2o duced by the steam whereby gasolene or other liquid is vaporized.

With the above and other objects view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made with in the scope of what is claimed, without departin from the spirit of the invention.

Int e drawings Figure 1 shows the invention in side elevation, parts being broken away Fig. 2 is an elevation showing one end of the structure;

' Fig. 3 is an elevation showing the other end of the structure; Fig. 4 is a fragmental section taken on the line 4-4 of Fig. 1; and

, Fig. 5 is a section taken on the line 5-5 of Fig. 1.

In the drawings, there is shown a supply tank 1, equipped with an inlet 2 and having a vent 3. At one end, the supply tank 1 is provided with a clean-out plug 4, the other end of the supply tank 1 carrying a gage glass 5. Below the supply tank 1 is a distillation tank6, A pipe 7 forms a communication between the supply tank 1 and the distillation tank 6, and enters the distillation alve seat 8 is an- ]Patented Dec. 4, 191%- 11 in the top of the supply tank 1. The up per exposed end of the rod 10 is pivoted eccentrically to a cam 12 adapted to cotiperate with the top of the supply tank 1. Mounted to reciprocate on the pipe 7 and located within the distillation tank 6 is a float 14. Pivoted to the float 14 are depending links 15 which, in their turn, are pivoted to the outer ends of levers 16 fulcrumed intermediate their ends on a frame 17 depending on the lower end of the pipe 7 The frame 17 includes a seat 17 adapted to cooperate with a downwardly closing valve 18 pivoted to the inner ends of the levers 16. At one end, the distillation tank 6 is supplied with a clean out door 19, the other end of the distillation tank carrying a gageglass 20. In the distillation tank 6 and located near to the top thereof, is a trough or collector 21. A ipe 22 is located exteriorly of the tank 6, an into the pipe 22 the trough 21 discharges. A. nozzle 23 enters the pipe 22 at its upper end. A cold water pipe 24 communicates with the nozzle 23 and carries a valve 25; A steam pipe 26'enters the tank 6, and, if desired, comprises a plurality of branches, each of the branches being equipped with perforations 27. Exteriorly of the distillation tank 6, the steam pipe 26 is equipped with a valve 28. i

Disposed below the distillation tank 6 is a condenser tank-29 in which is disposed a sinuous conduit comprising a plurality of inclined pipes 30 and headers 31 at the ends of the condenser tank 29. The upper end of the conduit defined by the pipes 30 and the headers 31 communicates with the lower end of the pipe 22. At one end of the condenser tank 29 and adjacent the top thereof is located a water discharge pipe 32. Disposed at the opposite end of the condenser tank 29 and entering the bottom thereof is a wa-.

'' tank 29 by the pipes 30, the lower end of the pipe 35 entering theseparator 34. Disposed within the separator ,34 is an upright outer sleeve 36, the upper end of which is secured to the top of the separator. The

side of the sleeve which is remote from the pipe 35 is provlded near to the top of the separator wlth an opening 37. Disposed within the outer sleeve 36 1821.11 inner sleeve llO is nearly filled with impure gasolene.

38 secured to the top of the separator. The inner sleeve 38 has a small air vent 38 near its top which prevents a siphoning action through the pipe 39 hereinafter mentioned. The lower ends of the sleeves 38 and 36 are spaced apart from the bottom of the separator 34. A water outlet 39 enters the bottom of the separator 34 within the inner sleeve 38. A gasolene outlet pipe 40 projects upwardly through the bottom of the separator 34 and extends between the outer sleeve 36 and the inner sleeve 38, the upper end of the pipe 40 being .located at a greater elevation than the upper end of the pipe 39. In the bottom of the separator 34 may be located a clean out plug 41.

Disposed beneath the condenser tank 29 and at the side of the separator 34 is an upright receiver which may be of circular contour. The receiver 42 is supplied with a gage glass 43, and with a drain 44 including a valve 45. At one side and intermediate its-ends, the receiver 42 is provided with a sampling cock 46. Access may be had to the receiver 42 by means of a plug 47. A pipe 48 enters the distillation tank 6, adjacent the bottom of the distillation tank, and leads to the receiver 42, the pipe opening into the receiver at a point near the top thereof.

The structure above described may be mounted upon a suitable frame 49, indicated in Fig. 1 of the drawings, but broken away, f

in order that the essential features of the invention may not be obscured, the specific structure of the frame being immaterial, should it be necessary to use a frame at all. The practical operation of the device is as follows:

Gasolene is permitted to flow into the tank 1 through the inlet 2, the cam lever 12 bein valve 9, whereupon the gasolenewill flow into the distillation tank 6 and by the pipe 48 Into the. recelver 42, until the receiver 42 quently the impure gasolene rises in the distfllation tank 6 until thefloat 14 rises andused only when the valve 18 fails to operate automatically. 1

Steam is introduced into the distillation tank 6 by way of the pipe 26, the steampassing outwardly into the distillation through the perforations 27, in the pipe. The steam. us introduced into the distillation tank 6, converts the gasolene therein into a moist vapor. The most of the dirt and other impurities remain in the tank 6. The gasolene vapor in the tank 6 passes by way of the collecting trough 21 into the pipe 22. By means of the nozzle 23 water 1s introduced into the upper end of. the pipe 22. This water, whlch 1s cold, exercises two functions. First, 1t serves to wash the vapor, and,

Subset.

'portance. closes the valve 18. The hand valve 9 is it creates a diminution of pressure in the pipe 22, so that. there is a tendency for the gasolene vapor to be sucked into the ipe 22, from the tank 6, by way of the troug 1 21.

From the pipe 22, the gasolene vapor passes into the sinuous conduit formed in the tank 29 by the pipes 30. The gasolene vapor is condensed by the water which has been admitted into the tank 29 through the water supply pipe 33. This condensation of the vapor further reduces the pressure in the pipe 22 and tends to create a suction through the pipe 22. From the lower end of the conduit formed by the pipes 30, gasolene flows through the pipe 35 into the separator 34. Dirt and impurities which remain in the gasolene, tend t gravitate at the bottom of the separator 4. The separator 34 contains water which stands as high as the top of the pipe 39. In the separator 34, the gasolene is compelled to traverse a round-about path on top of the water, the gasolene moving in opposite directions in two streams around the outside of the outer sleeve 36, and passing into the space between ing 37. The gasolene ultimately leaves by means of the pipe 40, in a clean condition. As the level of impure gasolene within the distillation tank 6 is lowered, the float '14 moves downwardly, opening the valve 18 and permitting impure gasolene to 'flow rom the supply tank 1 into the distillation tank 6. The operation of the device, there fore, is practically continuous.

' The water of condensation from the steam emitted by the steam pipe 26 is received by the tank 6, the water of condensation flowing by way of the pipe 48 into the receiver 42 which is filled with impure gasolene.

g The impure gasolene in the receiver 42 is manipulated to ralse the rod 10 and the replaced by water, the impure gasolene rising through the pipe 48 into the tank 6. The cock 46 may be opened, to permit a sampling of the contents of the receiver 42.

The distillation tank 6, the condenser 29 and the separator 34 are of primary im- It is desirable to use also the supply tank 1 and the receiver 42 to secure the most perfect results, but, if desired, either the supply tank 1 or receiver 42, or both of them, may be omitted at the will of the user.
